Impossible to find out. It's a highly kept secret...

Could you please explain exactly what you are looking for? Are you trying to find out the default configuration for the kernel installed by your distro?

If you have Intel/AMD, then you would have a kernel compiled for the x86 architecture.
www.kernel.org (http://www.kernel.org) is a great source of information.

I'm trying to find out for what cpu is my kernel compiled ... b/c as I understand there's great performance difference when kernel compiled to the right cpu ?

uname -s

There is a performance enhancement if you compile some of the x86 kernels more specifically to the x86 generation you have. By default, most distributions are compiled for i386 for reasons of compatibility. If you have anything better than an i386, you should compile for that platform.

If you are planning on compiling your own kernel, you have plenty of options for the different processors.
